I applied online. I interviewed at TikTok in Aug 2025
Interview
Horrible experience. The interviewer cannot clearly describe and explain the question. I am pretty sure he does not even understand the question and answer correctly. My suggestion is to be prepared and try more rehearsals before interviewing every candidate, and do not waste time.
three rounds, each has coding + ml basic + resume related questions
understand all the details in resume is important, since might go very deep down the project you have worked on
The first round was mainly a CV walkthrough.
The second round focused in depth on one specific project.
Both rounds also included LeetCode medium-level problems.
The third round was with the hiring manager with both project and problems for their business.
I applied through a recruiter. The process took 1 week. I interviewed at TikTok (San Jose, CA) in Mar 2026
Interview
one hour first round tiktok usds phone screen interview. past projects questions, leetcode mid questions, and machine learning, deep learning, large language model questions. And then ask the interviewer questions.
